SPECIFICATIONVformng part of Letters Patent No. 652,378, dated June 26,1900. Application filed June 3,1899.| Serial No. 719,186. (No model.)

To all whom t may concern,.-

Be it known that I, J oHN J. SULLIVAN, a citizen of the United States,residing at Ipswich, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Button-SewingMachines, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to that class of button sewing machines adaptedto automatically present shank-buttons to the needle, and comprisescertain improvements applicable to the machine shown by my Patent No.596,020, granted December 21,1897. The machine shown by my said patentwas provided with a presser-foot constructed to assist thebutton-feeder, which transfers the buttons from the lower end of thebutton-chute to the needle; but the present invention provides anattachment to the button-chute itself to assist in guiding the buttonsto the needle, this attachment forming practically a continuation orextension of the button-chute. The present invention also relates to astop on the presser-foot to limit the forward movements of the buttonsby the button-feeder, said stop being preferably adjustable, so that itsposition may be varied as may be required for use with buttons havingshanks of different sizes.

In the accompanying drawings, Figure lis a front side View of a portionof a buttonsewing machine equipped with the present improvements. Fig. 2is a rear side view, and Fig. 3 a front end view, of the same. Fig. t isa side view of the presser-foot, and Fig. 5 a bottoni view of the same.

In the drawings, A denotes the forward end part of the work-supportingarm or "cylinder of the machine and within which the shuttle and feedingmechanisms are arranged, and B denotes the lower portion of thebutton-chute,having a slot l) to receive the Shanks of the buttonspassing down said chute to the needle of the machine. The chute B isprovided with a Vsmall bracket b', to which is pivoted by a screw c anarm D, havinga buttonguiding portion d, provided with a buttonshank slotd', registering-0r communicating with or opening into the button-shankslot b of the chute B when the parts are in working position, said slotd' forming practicallya con tinuation of the said slot ZJ. The swingingbutton-feeder m is constructed and operated essentially the same as isthe correspondinglylettered part m of my Patent No. 596,020 and isautomatically moved at proper intervals to transfer the buttons one at atime from the button-chiite to sewing position beneath the needle n. v

E is the presser-foot, attached in the usual manner to the presser-barc, said foot being provided with a stop e', which is preferably adjustably attached to said foot by a set-screw e2 passing through a slote3 in the shank of said stop. The stop e is so located that its forwardend adjacent to the needle-recess e4 of the presser-foot will serve asan abutment against which the shanks of the buttons will impinge as theyare carried to sewing position beneath the needle by the button-feeder mand so that the needle can descend through and outside the eyes of thebutton-Shanks, and by adjustably attaching the said stop to thepresser-foot the position of said stop on said foot may be varied toaccommodate buttons of different sizes and having differentsizcd shanks.This button-stop, it will be understood, may be used on the form ofpresserfoot shown by my said Patent No.v596,020.

The hinged or pivoted button-guide d is preferably loosely connectedwith the'presserfoot, so as to be raised and lowered with said foot whenthe work is to be removed from the machine or after it has been placedin sewing position, this connection of said button-guide and foot beingeffected in the present instance by providing the said guide with asmall projection or lug d2, which enters a recess e5 in the side of thepresser-foot.

Having thus described my invention, I claim and desire to secure byLetters Patentl. In a button-sewing machine, the combination with abutton-chute having a buttonshank slot, of a button-feeder to transferbuttons from said chute to the needle, and a button-guiding devicemovably connected with the lower part of said chute and provided with abutton-shank slot or guideway communieating with or opening into thesaid buttonshank slot of said chute.

2. In a button-sewing machine, the combination with a button-chutehaving a button- IOO 2' waste shank slot, of a bn tton-feeder totransfer buttons from said chute to the needle, and apivotally-supported button-guiding device movably connected with thelower part of said chute and provided with a button-shank slot orguideway communicating with or opening into the said button-shank slotof said chute.

3. In a button-sewing machine, the combination with a button-chutehaving a buttonshank slot, of a button-feeder to transfer buttons fromsaid chute to the needle, apresserfoot, and a button-guiding devicepivot-ally, connected to the lower part of said chute and provided witha button-shank slot or guide` way communicating with or opening into thesaid button=shank slot of said chute, said but= ton-guiding device beingloosely connected with said presser=foot so as to be lifted and loweredtherewith.

4. In a button-sewing machine, the combination with the button-feedingdevice thereof., ofv a presser-foot provided with a stop located in theline of movement of the buttonu Shanks and serving as an abutment t-olimit the forward feeding movement of the buttons by their Shanks so asto locate saidshanks `properly relative to the needle.

'5. In a button-sewing machine, the combination with the button-feedingdevice thereof, of a presser-foot provided with a stop lof cated in theline of movement of the button Shanks and serving as an abutment tolimit the forward feeding movement of the buttons by their Shanks so asto locate the Shanks properly relative to the needle, said stop beingadjustably attached to said presser-foot so that its position may bevaried for dierent-sized button-Shanks.

6. In a button-sewing machine, the combination with the button-feedingdevice thereof, of a stop located in the path of movement of thebutton-Shanks and adjacent to the line of movement of the needle andserving as an abutment to limit the forward feeding movement of thebuttons by their Shanks so as to locate the Shanks properly relative tothe needle.

In testimony whereof I aix my signature i in `the presence of twowitnesses.
